The head articulates with the os coxae at the acetabulum and the condyles articulate with the tibia at the tibial condyles. Patellar surface forms a joint with the facets for the medial and lateral condyles on the patella.

Head of the Femur

Medially projecting "ball" at the top of the femur which inserts into the acetabulum.

Fovea Captis

Ligamentum teres runs from this pit to the acetabulum.

Neck (Femur)

Hourglass-shaped bar of bone connecting the head and shaft of the femur.

Greater Trochanter (Femur)

Large, lateral curl of bone at the junction of the shaft and neck of the femur.

Attachment site for thigh and buttock muscles.

Lesser Trochanter (Femur)

Medially projecting lump inferior to the neck of the femur.

Attachment site for thigh and buttock muscles.

Intertrochanteric Line (Femur)

Broad, low ridge of bone connecting the trochanters of the femur on its anterior aspect.

Intertrochanteric Crest (Femur)

Sharp ridge of bone connecting the trochanters of the femur on its posterior aspect.

Gluteal Tuberosity

Vertical ridge just inferior to the intertrochanteric crest on the posterior aspect of the femur. Eventually blends into the linea aspera inferiorly.

Site of muscle attachment.

Linea Aspera

Long vertical ridge on the posterior aspect of the femur's shaft.

Blends into the gluteal tuberosity superiorly and diverges into the medial and lateral supracondylar lines inferiorly.

Site of muscle attachment.

Medial Supracondylar Line (Femur)

Medial inferior branching of the linea aspera on the posterior aspect of the femur's shaft.

Site of muscle attachment.

Lateral Supracondylar Line (Femur)

Lateral inferior branching of the linea aspera on the posterior aspect of the femur's shaft.

Site of muscle attachment.

Lateral Condyle (femur)

Lateral lump on the distal end of the femur which articulates with the tibia.

Medial Condyle (Femur)

Medial lump at the distal end of the femur which articulates with the tibia.

Medial and Lateral Epicondyles (Femur)

Lateral lumps which flank the condyles of the femur superiorly.

Sites of muscle attachment.

Adductor Tubercle (Femur)

Medially projecting bump on the superior surface of the medial epicondyle of the femur.

Patellar Surface

Smooth surface between the condyles of the femur where the femur articulates with the patella.

Patella

Triangular bone enclosed in the tendon that secures the thigh muscles to the tibia.

Projects the knee joint anteriorly and improves the leverage of the thigh muscles acting across the knee.

Articulates with the femur.

Facet for lateral condyle of femur

Smooth, lateral plate on the posterior aspect of the patella.

Facet for medial condyle of femur

Medial flat plate on the posterior surface of the patella.

Surface for patellar ligament

Inferior flat space on the posterior aspect of the apex of the patella.

Apex of the Patella

V formed by the inferior angle of the patella.

Tibia

Medial bone of the leg.

Receives weight of the body from the femur and transmits it to the foot.

Articulates with the femur, fibula, and talus.

Medial and Lateral Condyles (Tibia)

Medial and lateral protrusions on the bulbous proximal end of the tibia.

Have concave superior surfaces which articulate with the corresponding condyles of the femur.

Intercondylar Eminence (Tibia)

Irregular upward projection separating the lateral and medial condyles of the tibia.

Tibial Tuberosity

Rough lump on the anterior aspect of the tibia, just inferior to the condyles.

Attachment site of patellar ligament.

Anterior Crest/Anterior Border (Tibia)

Long ridge which runs the length of the anterior aspect of the shaft of the tibia.

Anterior "point" of the triangle which is formed by the tibia in cross-section.

Medial Malleolus

Medial bulge of the ankle.

Downward/medial projection at the distal end of the tibia.

Fibular Notch

Notch on the lateral surface of the tibia which participates in the distal tibiofibular joint.

Fibula

Lateral bone of the leg. Sticklike with slightly expanded ends.

Articulates proximally and distally with the lateral aspects of the tibia. Also articulates with the talus via the lateral malleolus.

Head of Fibula

Lumpy portion at the proximal end of the fibula.

Lateral Malleolus

Lateral ankle bulge that is the distal end of the fibula.

Articulation point of the fibula and the talus.

Interosseous Membrane

Membrane between the tibia and the fibula

Proximal Tibiofibular Joint

Joint between the head of the fibula and the fibular notch of the tibia.

Most lateral carpal situated entirely in the distal row (although it is hugged laterally by the cuboid). Oval shaped.

Articulates with the navicular, cuboid, intermediate cuneiform, and ?metatarsals 3 and 4?

Metatarsals (Bones of the Metatarsus)

Bones of the "ball" and anterior half of the arch of the foot.

Numbered 1-5 starting at the medial (big toe) side.

Articulate with each other laterally/medially, with the tarsals posteriorly, and with the proximal phalanges anteriorly.

Phalanges

14 toe/lower limb digit bones.

Each toe is made up of distal, middle, and proximal phalanges which articulate in series. (Exception: hallux is only distal and proximal--no middle phalanx). The proximal phalanges articulate posteriorly with the metatarsals.

Hallux

"Big toe."

Only has distal and proximal phalanges--no middle phalanx.

Transverse Arch

Arch cutting horizontally across the sole of the foot.

Medial Longitudinal Arch

Deep arch along the medial edge of the foot from heal to big toe.

Lateral Longitudinal Arch

Shallow arch along the lateral edge of the foot from the heel to the pinky toe.
